To all whom 'it 'may concern:

Be it known that I, HUGO GoT'rsoHALK, a citizen of the United States, residing .at Burnham, in the county of Mifflin, State of Pennsylvania, have inventeda new and useful Pan Cleaning and Greasing Machine, of which the following is a specification.

This invention relates to an apparatus for cleaning and greasing pans of the type generally used in the baking of bread or cake and has for an object the removal of bread crust, cake crust, or other undesirable substances from the ans.

It consists of a series of spindles carrying brushes adapted to be rotated and so mounted as to extend well Within a pan which is to be cleaned and reach every corner and portion of the interior thereof.

It further consists of a seriesof spindles carrying brushes which are ada ted to be inserted within a pan and s rea a coating of grease uniformly throug out the interior surface thereof.

' It further consists of other novel details of construction, all as will be hereinafter fully set forth.

For the purpose of ex laining my invention, the acco'm anying dlfawing illustrates a satisfactory re uction of the same to practice, but the important instrumentalities t ereof may be varied so it is to be understood that the invention is not limited to the specific arran ement and organization shown and describe Figure 1 re resents a vertical section of a complete mac 'ne embodying my invention. Fig. 2 represents a vertical section in side elevation on line x-x, Fig. 1. Fi 3 represents a perspective view in detail o the brush spindle. Fig. 4 represents a -section on line 'tz/ y, Fig. 1. Fig. 5 represents a perspective 4 View of one of the f greasingbrushes.k Fig. 6

represents a view of the device in use.

Similar numerals of reference indicate correslponding parts in the figures. eferring to the drawings: 1 and 1l designate brush carrying spindles suitably mounted on bearing osts 2 and ada ted `to be rotated in any suitable manner. n the present instance a gear 3 is keyed respectively to the spindles 1 and 1 and meshes with a gear 4 secured to the driving shaft 5.

The spindle '1 carries thereon a cleaning `brush 6 which is preferably formed in two segments as shown i'n Fig.` 2 in order that any dirt or dust collected in the cleaning of a pan pressing it firmly thereagainst.

`maylfesca e. between theseg'ments of the lbrush;*j-"ilhe spindle-1l carries a somewhat similarl brush k7 adaptedto receive a coating of grease which itapplies'to. the pans and in order toproduce a uniform spreading of the sameis preferably made in three segments asillustrated in Fi 5.

fAttention is ca ed to the fact that the spindles carrying the sets of brush segments are raised a sufficient distance above the supporting table 8 in order that a bread pan 9 ma be lowered over a brush and inclose loot the'spindle and brush ,on the inside thereof and by tilting the pan back and forth every corner of the pan may be reached and cleaned. This feature of the raised s indie is a very important one, allowing as it oes the brush to entirely enter the pan and clean every ortion thereof. As the ans for which t 's machine is'adapted to c ean and grease are usually connected in pairs or a series of four pans, the brushes 'are usually mounted on a seriesof s. indlesl as shown in Fig.,2 and thegears 4 p aced4 in mesh .with one another so as to produce a rotation of each brush throughout the series. It will be noted on ve brushes may e employed for each pan. The o eration of the `greasing brushes is exactly tliie same in that they are mounted similarly and also extend com letely Within the pan;

The operation of t e device is exactly the same whether one or a pluralit used and consists of rotating tlie brush and lowering a pan first over the cleaning set so that the pan completely incloses the brush and the spindle then it is -tilted backward and forward over the brush at the same time The pan is then removed and in the same manner lowered over and held against the greasing large wide pans two or more of pans are A brushes which apply a thin coat of grease to the inside of the pan. By m novel cleaning and greasing device I am ab e to thoroughly clean the pans and do the same in a minlmum amount of time while in the greasing process the pans are evenly coated and a like amount of i grease placed uponeach pan which has been impossible to perform by the greasing means heretofore in use.

' I preferably form the supports or bearing posts 2 with the yokes or Journals for the shafts 1, so that/ the same can be simply dropped thereinto, the brushes 6 or 7 belng provided with the extendin collars for holdlng the same supported on t e shafts and the end brushes being preferably rovided With set screws, as shown in Fig. 5, fldrholding the parts in position.

Having thus described my invention, what I claim as new and desirel to secure by Letters Patent, is:-

1. 'In a pan cleaning and greasin machine, a lurality of spindles, a plura ity of segmenta l brushes on each spindle, a driving shaft, gearing cooperating therewith to rotate said splndles and supports whereby each set of brushes may be inclosedv Within a bakn pan.

2. Ign a pan chine, a plurality of spindles, a plurality of segment brushes spaced apart on each spincleaning and -greasing madle, a Adriving shaft, earing cooperating therewith to rotate sai spindles and supports whereby each set of brushes may be inclosed Within a baking an. l

3. In a device of the c aracter described, a spindle, fa brush thereon comprising a plurality of sets of segments, a driving shaft adjacent said spindle, a plurality of-supports for said spindle, earing intermediate said suports and said brush segments, and a set of rush segments exterior of each support.
